Post-Compensation Method for Motion Errors of Rotating Accelerometer Gravity Gradiometer

1. A post-compensation method for motion errors of a rotating accelerometer gravity gradiometer, comprising the following steps of: processing output data from the rotating accelerometer gravity gradiometer; filtering output data, linear motion data and angular motion data of the rotating accelerometer gravity gradiometer converting the output data, the linear motion data, and the angular motion data to have a same sampling rate; reducing data noise of the output data, the linear motion data, and the angular motion data by: 1) dividing the output data, the linear motion data, and the angular motion data of the rotating accelerometer gravity gradiometer with a total exploration time length of L hours into N data blocks by time, wherein time lengths of the N data blocks are different; 2) removing linear and angular motion errors from the N data blocks sequentially; 3) combining and then demodulating the N data blocks after the linear and angular motion errors are removed; 4) outputting a gravitational gradient with the total exploration time length of L hours.

2. The post-compensation method for the motion errors of the rotating accelerometer gravity gradiometer according to claim 1 , wherein the methods in step 2 for removing the linear and angular motion errors from the N data blocks are the same.
